DETAILED DESCRIPTION

As discussed in detail below, conventional video calling applications may inconvenience users by not allowing three or more participants to see each other on the display screens. The systems and methods described herein have been devised to address these challenges.

FIG. 1 illustrates a mobile computing device 12 that includes a housing 14, which, for example, may take the form of a casing surrounding internal electronics and providing structure for displays, sensors, speakers, buttons, etc. The housing 14 is configured to include a processor 16, volatile storage device 18, sensor devices 20, non-volatile storage device 22, and two or more display devices 24. The mobile computing device 12 may, for example, take the form of a smart phone device. In another example, the mobile computing device 12 may take other suitable forms, such as a tablet computing device, a wrist mounted computing device, etc.

Turning to FIG. 2A, an example mobile computing device 12 is illustrated. As shown, the example mobile computing device 12 includes a housing 14. As discussed above, the housing 14 may be configured to internally house various electronic components of the example mobile computing device 12, including the processor 16, volatile storage device 18, and non-volatile storage device 22. Additionally, the housing 14 may provide structural support for the display devices 24 and the sensor devices 20. The sensor devices 20 may include a plurality of different sensors, such as, for example, an accelerometer 26, forward facing cameras 30A and 30B, etc. The sensor devices 20 may also include a capacitive touch sensor 34, such as a capacitive array that is integrated with each of the two or more display devices 24. In another example, the sensor devices 20 may include camera-in-pixel sensors that are integrated with each of the two or more display devices 24. It will be appreciated that the examples listed above are exemplary, and that other types of sensors not specifically mentioned above may also be included in the sensor devices 20 of the mobile computing device 12. In the illustrated example, the sensor devices 20 include one or more accelerometers 26 that are contained by the housing 14. The sensor devices 20 may further include forward facing cameras 30A and 30B. In one example, the forward-facing cameras 30A and 30B include RGB cameras. However, it will be appreciated that other types of cameras may also be included in the forward-facing cameras 30A and 30B. In this example, forward facing is a direction of the camera's associated display device. Thus, in the example of FIG. 2A, as the screens for both of an example pair of display devices 24A and 24B are facing the same direction, both of the forward-facing cameras 30A and 30B are also facing the same direction.

As shown, the sensor devices 20 may also include capacitive touch sensors 34 that are integrated with the pair of display devices 24A and 24B, as well as other additional displays. In the illustrated embodiment, the capacitive touch sensors 34 include a capacitive grid configured to sense changes in capacitance caused by objects on or near the display devices, such as a user's finger, hand, stylus, etc. In one embodiment, the capacitive touch sensors 34 may also be included on one or more sides of the mobile computing device 12. For example, the capacitive touch sensors 34 may be additionally integrated into the sides of the housing 14 of the mobile computing device 12. While the capacitive touch sensors 34 are illustrated in a capacitive grid configuration, it will be appreciated that other types of capacitive touch sensors and configurations may also be used, such as, for example, a capacitive diamond configuration. In other examples, the sensor devices 20 may include camera-in-pixel devices integrated with each display device including the pair of display devices 24A and 24B. It will be appreciated that the sensor devices 20 may include other sensors not illustrated in FIG. 2A.

In the example mobile computing device 12 illustrated in FIG. 2A, the two example display devices 24A and 24B are movable relative to each other. As shown, the example mobile computing device 12 includes a housing 14 including the processor 16, the accelerometer 26, and the two or more display devices 24, the housing including a hinge 36 between a pair of display devices 24A and 24B of the two or more display devices 24, the hinge 36 being configured to permit the pair of display devices 24A and 24B to rotate between angular orientations from a face-to-face angular orientation to a back-to-back angular orientation.

In one implementation, the face-to-face angular orientation is defined to have an angular displacement as measured from display to display of between 0 and 90 degrees, an open angular orientation is defined to be between 90 and 270 degrees, and a back-to-back orientation is defined to be from 270 to 360 degrees. Alternatively, the face-to-face angular orientation may be defined to be between 0 and 180 degrees and the back-to-back angular orientation may be defined to be between 180 and 360 degrees. In either of these implementations, when tighter ranges are desired, the face-to-face angular orientation may be defined to be between 0 and 60 degrees, or more narrowly to be between 0 and 30 degrees, and the back-to-back angular orientation may be defined to be between 300 and 360 degrees, or more narrowly to be 330 and 360 degrees. The zero degree position may be referred to as fully closed in the fully face-to-face angular orientation and the 360 degree position may be referred to as fully open in the back-to-back angular orientation. In implementations that do not use a double hinge and which are not able to rotate a full 360 degrees, fully open and/or fully closed may be greater than zero degrees and less than 360 degrees.

Now turning to FIG. 2B, the hinge 36 permits the pair of display devices 24A and 24B to rotate relative to one another such that an angle between the pair of display devices 24A and 24B can be decreased or increased by the user via applying suitable force to the housing 14 of the mobile computing device 12. As shown in FIG. 2B, the pair of display devices 24A and 24B may be rotated until the pair of display devices 24A and 24B reach a back-to-back angular orientation as shown in FIG. 2C.

As illustrated in FIG. 2C, while in an angular orientation where the pair of display devices 24A and 24B are in a back-to-back angular orientation, the pair of display devices 24A and 24B face away from each other. Thus, while using the mobile computing device 12, the user may only be able to view one of the display devices of the pair of display devices 24A and 24B at a time. Additionally, while in a back-to-back angular orientation, sensor packages of the sensor devices, which may each include forward facing cameras 30A and 30B, also face in the same direction as their respective display device, and thus also face away from each other. Alternatively, back-to-back orientation may be defined as a rotational angle range, between 270 and 360 degrees and between 310 and 360 degrees, for example.

As shown in FIG. 2D, the angular orientation between the pair of display devices 24A and 24B may also rotate to a face-to-face orientation where the pair of display devices face each other. Such an angular orientation may help protect the screens of the display devices.

Turning back to FIG. 1, the processor 16 is configured to execute a computer program 38, which, for example, may be an operating system or control program for the mobile computing device, and one or more application programs 40 stored on the non-volatile storage device 22, and to enact various control processes described herein. In some examples, the processor 16, volatile storage device 18, and non-volatile storage device 22 are included in a System-On-Chip configuration.

The computer program 38 executed by the processor 16 includes an orientation module 42. As shown in FIG. 1, the orientation module 42 is configured to receive sensor data 54 from the sensor devices 20. Based on the sensor data 54, the orientation module 42 is configured to detect a current angular orientation 56 between the pair of display devices 24A and 24B indicating that the pair of display devices 24A and 24B are facing away from each other. As discussed previously, the angular orientation between the pair of display devices 24A and 24B may rotate through angular orientations between a face-to-face angular orientation to a back-to-back angular orientation. Thus, the orientation module 42 is configured to detect a current angular orientation 56 indicating that the pair of display devices 24A and 24B are facing away from each other, such as a back-to-back angular orientation.

The orientation module 42 may be configured to detect the current angular orientation 56 based on different types of sensor data. In one embodiment, the sensor data 54 may include accelerometer data received via the accelerometers 26. As the user applies force to the housing 14 of the mobile computing device 12 to rotate the pair of display devices 24A and 24B, the accelerometers 26 will detect the resulting movement as angle sensors. Thus, based on accelerometer data for a new rotation and a previously known angular orientation between the pair of the display devices 24A and 24B, the orientation module 42 may calculate a new current angular orientation 56 resulting after the user rotates the pair of display devices 24A and 24B around the hinge 36. However, it will be appreciated that the current angular orientation 56 may also be calculated via other suitable methods. For example, the sensor devices 20 may further include an angle sensor such as a hinge angle sensor in the hinge 36 that is coupled to the hinge and configured to detect an angular orientation of the hinge 36, and thereby detect a current relative angular orientation or relative angular displacement of the pair of display devices 24A and 24B. Alternatively, the angle sensor a pair of inertial measurement units, such as accelerometers 26.

Referring to FIGS. 3A and 3B, an example use case illustrating aspects of the present disclosure will now be presented. A first user 13A may be capturing live video images of a third user 13C using camera 30A facing the third user 13C, executing a video calling application 40 that displays live video images of the third user 13C on both display devices 24A and 24B so as to stream a video feed when the mobile computing device 12 is in a back-to-back angular orientation. Simultaneously, camera 30B is capturing live video images of the first user 13A operating the mobile computing device 12 so as to stream a video feed. At the same time, as depicted in FIG. 3B, a second user 13B is in a separate location using a mobile computing device 112, which has established a data connection with mobile computing device 12 through a network, executing a separate instantiation of the video calling application 140, capturing video of the second user 13B using camera 130 facing the second user 13B so as to stream a video feed. Simultaneously, the display 124 of the mobile computing device 112 concurrently displays live video images of the first user 13A captured by camera 30B, live video images of the third user 13C captured by camera 30A, and live video images of the second user 13B captured by camera 130. The video calling application 140 receives live video image data from the both cameras 30A and 30B of mobile computing device 12, and simultaneously sends live video image data from camera 130 to mobile computing device 12. The live video image data from camera 130, received by the mobile computing device 12, is then concurrently displayed on both display devices 24A and 24B so as to be visible to both the first user 13A and the third user 13C. Accordingly, each participant in the three-way video calling session is able to view all three participants, including themselves, either on a display screen or in direct line-of-sight between users.

Referring to FIGS. 4A and 4B, a transition between a one-on-one video mode (two-way mode) and a three-way video mode (group video chat mode) in the example use case of FIGS. 3A and 3B will now be illustrated. In FIG. 4A, the first user 13A (user A) and the second user 13B (user B) are chatting on a video calling application in camera mode that is a two-way mode, where camera 30B is capturing live video images of the first user 13A, and camera 130 is capturing live video images of the second user 13B. Accordingly, live video images of both the first user 13A and the second user 13B are displayed on displays 24A and 124 in split screen. But as soon as a predetermined trigger condition is satisfied, the video chat application transitions the camera mode from a one-to-one mode to a three-way video mode in which live video images of three users are visible as live streaming video on each display of the display devices used by each of the three users, as depicted in FIG. 4B. The predetermined trigger condition is preferably the sensing of the back-to-back orientation of the hinged display device 12.

Unlike the one-on-one video calling feature depicted in FIG. 4A, the group video chat mode depicted in FIG. 4B allows three users to appear in split-screen at the same time on each display of the display devices used by the three users. Upon detecting the predetermined trigger condition, camera 30A of the hinged display device 12 starts capturing live video images of a third user 13C (user C), and live video images of the first user 13A, the second user 13B, and the third user 13C are displayed on displays 24A, 24B, and 124. It will be appreciated that other video calling application features may be visible as live video images of the users are being displayed on the displays, such as instant text messaging boxes (illustrated in FIGS. 4A and 4B) and live screenshot images of the displays (not illustrated). Further, the group video chat session may be broadcast to other users such that the live video images of all three users are visible to other users through live video streaming. The other users may then be able to listen to and view the three users, and may participate in the group video session by sending content (text messages, images, video clips, emojis, and emoticons, for examples) and/or listening and talking over during the group video chat session. Further, the group video chat mode of the video calling application may be configured to display live video images of a fourth user and even a fifth user if the displays can accommodate and display split screen images of four or five users on the displays.

FIG. 5 is a schematic illustration of a first display device 12, executing a video calling application 40, interacting with a second display device 112 executing another instantiation of the video calling application 140. The display devices 12 and 112 may be communicatively coupled to each other via a wired connection or a wireless connection to a network. In some examples, the network may take the form of a local area network (LAN), wide area network (WAN), wired network, wireless network, personal area network, or a combination thereof, and may include the Internet. In the example of FIG. 5, the first display device 12 is communicatively coupled to the second display device 112 via one or more networks. In other examples, the display devices may also be operatively connected with additional devices.

The one or more processors of the first display device 12 execute a program 38 to determine that the device has satisfied a predetermined trigger condition, and receive and process sensor data from the cameras 30A and 30B. The predetermined trigger condition is in one example the sensing of the back-to-back orientation of the device. However, the predetermined trigger condition is not particularly limited, and the initiation of the three-way calling method may alternatively be the sensing of a user input, a user operation of a physical or virtual button on the device, a scheduled timing, and/or input by a remote user, for example. Nevertheless, the sensing of the back-to-back orientation of the device as the predetermined trigger condition is preferable for the hinged display device 12 due to the simplicity of user operation. The program 38 may be program logic of an operating system, for example. The one or more processors of the first display device 12 may apply program logic of a video calling application 40. Upon establishing a data connection with the second display device 112, the video calling application 40 sends live video image data 60 from camera 30A and camera 30B to the video calling application 140 executed by the second display device 112, and receives live video image data 62 from camera 130 of the second display device 112. The application 40 subsequently causes both display devices 24A and 24B to concurrently display live video images captured by cameras 30A, 30B, and 130.

The one or more processors of the second display device 112 execute a program 138 to receive and process sensor data from the camera 130. The program 138 may be program logic of an operating system, for example. The one or more processors of the first display device 12 may also apply program logic of a video calling application 140. Upon establishing a data connection with the first display device 12, the video calling application 140 receives live video image data 60 from camera 30A and 30B on the first display device 12, and sends live video image data 62 from camera 130 of the second display device 112. The application 140 subsequently causes the display device 124 to concurrently display live video images captured by camera 30A, camera 30B, and camera 130.

Although the embodiment of FIG. 5 describes the displays 24A and 24B as displaying image data from cameras 30A, 30B, and 130, and the display 124 as displaying image data from cameras 30A, 30B, and 130, it will be appreciated that the video calling applications 40 and 140 may also have user customizable settings to change display settings for each of the display devices depending on user preferences. Each of the display devices 24A, 24B, and 124 may be separately configured and customized to concurrently display any permutation of image data: for example, display only image data from one of cameras 30A, 30B, and 130; display any two of image data from cameras 30A, 30B, and 130; or display image data from all three cameras 30A, 30B, and 130 according to user preferences.

FIG. 6 illustrates a method 600 for sharing and displaying image data between two mobile computing devices based on hinge movement. The following description of method 600 is provided with reference to the software and hardware components described above and shown in FIGS. 1-5. It will be appreciated that method 600 also may be performed in other contexts using other suitable hardware and software components.

With reference to FIG. 6, at 602 the method 600 may include the program in the first display device receiving sensor data (live video image data) from camera 30A. At 604 the video calling application may be configured to cause display 24A to display live video image data from camera 30A. At 606 the video calling application sends live video image data from camera 30A to the second display device. At 608 the video calling application receives live video image data from camera 130 of the second display device. At 610 the video calling application subsequently causes display 24A to display live video image data from camera 130 concurrently with the display of live video image data from camera 30A.

At 612 the orientation module may calculate a current angular orientation of the multi-screen device based on the sensor data from the hinge angle sensor or accelerometers and determine if the first display device is in a back-to-back angular orientation, in which cameras 30A and 30B face opposite directions. If the first display device is determined not to be in a back-to-back angular orientation, at 612 the video calling application is configured to return to step 602. If the first display device is determined to be in a back-to-back angular orientation, at 614 the program in the first display device receives image data from camera 30B. At 616 the video calling application subsequently moves into a group video chat mode and causes display 24B to display live video image data from camera 30B concurrently with the display of live video image data from cameras 30A and 130. At 618 the video calling application sends live video image data from camera 30B to the second display device. Then the method 600 returns to step 602.

Further with reference to FIG. 6, at 620 the method 600 may include the program in the second display device receiving sensor data (live video image data) from camera 130. At 622 the video calling application may be configured to cause display 124 to display live video image data from camera 130. At 624 the video calling application sends live video image data from camera 130 to the first display device. At 626 the video calling application receives live video image data from camera 30A of the first display device. At 628 the video calling application subsequently causes display 124 to display live video image data from camera 30A concurrently with the display of live video image data from camera 130. At 630 the video calling application receives live video image data from camera 30B. At 632 the video calling application subsequently causes display 124 to display live video image data from camera 30B concurrently with the display of live video image data from cameras 30A and 130. The method 600 then returns to step 620.

It will be appreciated that the reception and display of image data from the cameras are executed in real-time so that a seamless video calling experience is achieved for all three users operating the first display device and the second display device. Thus, the cameras 30A, 30B, and 130 perform simultaneous video recording in real-time. Further, since the predetermined trigger condition for transitioning from a one-on-one video mode to a group video chat mode is the sensing of a back-to-back orientation of the hinged display device, the user can easily switch between video modes using a simplified user operation.

Although the embodiments depicted in FIGS. 3A, 3B, 4A, 4B, 5, and 6 describe the second display device 112 having only one display 124 and one camera 130, it will be appreciated that the number of display devices and cameras on the second display device 112 is not particularly limited, and may include two cameras and two display devices like the first display device 12, for example. In such examples, image data from the two cameras of the first display device 12 and image data from the two cameras of the second display device 112 may be shared between the two mobile computing devices. Furthermore, each of the four display devices in the two mobile computing devices may be subsequently configured and customized by the user to display any permutation of image data: for example, display any one, two, three, or all four of image data from the four cameras according to user preference. Image data may also include audio data as well as streaming video data. Accordingly, the multi-screen device provides viewfinders for users of the multi-screen device to let them know that the video recording is effectively framed according to their preferences (with the correct image zoom and background view, for example), and also provide video images of at least one remote user participating in the video call, so that a seamless, enhanced video calling experience is achieved for all participants, with all the participants being able to see each other in real-time without missing any facial reactions.
